All children who were simultaneously wasted and stunted were also underweight. The maximum possible weight-for-age z-score in these children was below − 2.35. Low WHZ and low HAZ have a joint effect on WAZ which varies with According to its description, . . . weight-for-age Z-scores are calculated for children 0 to 5 years of age. If the age, height or weight values are outside the range of reference values, a value of 99 is given for the corresponding z-score (s). It appears that you cannot use this program for children older than 5. Percentile conversion from Z-Score is done by table look-up in the standard Normal Table. Percentiles are provided for Z Scores between -3.09 and 3.09. Values beyond these extremes return percentiles of 0.1 and 99.9 respectively.

Rapid infant growth was defined as a weight-for-age z-score (WAZ) change greater than 0.67 between birth and 12-months of age. Measures of infant growth included change in WAZ, weight-for-length z-score (WLZ), and body mass index (BMI) z-scores from birth to 12-months and infant anthropometrics at 12-months (weight, skinfold thickness).

The percentile shows how your infant's weight compares to other infants of the same length. The percentile tells you what percentage of babies weigh less than your baby. For example out of a sample of 100 babies, a percentile value of 40 percent means your baby weighs more A z-score measures the distance between a data point and the mean using standard deviations. Z-scores can be positive or negative. The sign tells you whether the observation is above or below the mean. For example, a z-score of +2 indicates that the data point falls two standard deviations above the mean, while a -2 signifies it is two standard Anthropometrics using weight for age (WFA), height for age (HFA), and body mass index for age (BMI/A), which is measured from 2 to 5 years Z scores using WHO z-scores using Anthro software of The mean wt for age z scores was −1.90 (SD: 0.97) z scores MD 0.07 z scores lower (0.18 lower to 0.05 higher) Length or height for age z scores follow-up: 6 mo 1258 (1 RCT) ⨁⨁⨁ Moderate e — The mean length or height for age z scores was −1.95 (SD: 0.99) z scores MD 0.12 z scores higher (0.02 higher to 0.21 higher) Fetal growth, typically measured as birth weight for gestational age (BW-for-GA), is an important clinical indicator of perinatal morbidity, survival, and long-term health outcomes in children and their mothers. 1 Clinicians often use percentile thresholds (eg, ≤10th or ≥90th) of BW-for-GA from population-based references to identify at-risk infants who may have had restricted or excessive .
